  No, actually, it doesn't explain it very well at all, at least not as far as
I can tell.

  What is the "test" file you're trying to open?  Is it a text file, or is it
the binary you have compiled from the source code above?  Or something else?

  Is the file on the local hard disk, or is it on a network file system disk? 
If so, what kind of network file system?  NFS?  AFS?  Something else?

  If you're talking about a network file system, then is the file local on
either of the machines you're running it on, or is it on a third-party
fileserver?

  And I'm assuming that when you say "node," you mean machine on the network. 
Is that correct?
